  • What is a withholding variation?

    Under tax law, the Commissioner of Taxation may vary the amount a payer is required to withhold from a withholding payment, to meet the special circumstances of a particular case or class of cases.

    The main purpose of varying your rate or amount of withholding is to make sure that the amount withheld during the income year best meets your end-of-year tax liability. For example, you may want to apply for a variation if the normal rate of withholding leads to a large credit at the end of the income year because your tax-deductible expenses are higher than normal.

    If you believe your circumstances warrant a variation of the rate or amount of withholding, you will need to determine whether the variation is upwards or downwards.

    Note: The granting of a variation does not mean that we have accepted the tax treatment of the income and deductions in your application – your actual tax liability will be determined when you lodge your income tax return. Under tax law, you must keep records of your relevant income and expenditure for a minimum of five years.

    Upward variations

    You can ask your payer to increase the amount of withholding from your income.


    Keith is retired and receives an annual superannuation pension income of $25,000. He also receives interest on his term deposit. Keith estimates his interest will be $1,000. So, his estimated taxable income will be $26,000 ($25,000 + $1,000). Keith can apply for a variation to have his withholding rate calculated based on his estimated taxable income of $26,000.

    End of example

    How to apply for an upward variation

    You can arrange an upward variation by entering into an agreement with your payer to vary the rate or amount of withholding. Your request should be in writing, but can be in any format – you can send an email request; or you can use a paper or computer-based form.
